I do a lot of drafting using AutoCAD 2000 LT on Windows XP, but I need to upgrade to a newer operating system (Windows 8). Unfortunately, AC2000 won't work. So, I am looking for a new free (no money) alternative that is:
- Fast: I need to be able to modify some really large files
- Is customizable: whether this means that it is Open-Source in C#/Java so I can mess with it's inner code, or is really robust for add-ons, I need to be able to add functionality.
- Complete: So many of the projects I have found have either been abandoned, or are on such an early stage that they are very unstable.
Extras would be touch support, coded in C#, and things like XREFs.
Does anyone know of such software?
